I just read an article on lemonde.fr about the French police trying to break open an iPhone and saw this:
six téléphones sur les 141 analysés en 2014 « n’ont pu être traités »
And could anyone be kind enough to explain a bit as to why it wasn't
n'ont pas pu être traités?
what sort of grammatical thing do we call this (just so that I can have a term to google on in the future) ?
